SLED.

Application filed July 9, 1923. Serial No'. 650,373.

To all 'whom it 12mg/ cwwam: l

Be it known that I, Im: L. ROBBmm, a

citizen of the United States, residing at Southbridge, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Sleds, of which the following is a specification.

This invention relates to sleds, and has for its leading object thelprovision of a device which will serve to add to and increase thespringiness of a coasting sled, whereby the sled will have considerablymore elasticity and spring in its action when taking bumps or boundsthan is-present in the ordinary type ofcoasting sled.

A further object of the present invention is the provision of adjustingmeans whereby the springiness or elastic action of the seatingarrangement may be adjusted and regulated within certain limits.

A further object 'of the invention is the provision of a device of thischaracter in which the parts shall be so related that the elastic orspring action of the sled may be increased or decreased within certainlimits and av sport toyA provided having characteristics not possessedby prior devices.

Other objects and advantages of the invention should be readily apparentby reference to the following specification take-n in connection withthe accompanyin drawings, and it will be understood t at anymodifications or departures may be made from the specific featuresdisclosed within the scoIe of the claim without 'departing from orexceeding the spirit of the invention, a preferred form only of thedevice being shown for sake of and by way of illustration.

Figure I is a perspective view of the in vention, showing the forwardend of the runner flexed or bent up by the weight of the user.

Figure II is a side elevation of the 1nvention showing in dotted linesthe spring action of the same.

Figure III is a partial longitudinal cross vsection on line III-III ofFigure I.

Figure IV is a cross section on line IV-IV of Figure II.

Referring to the drawings, 1 is a base or runner board, which isstraight, as shown in dotted lines in Figure II, whenrelieved of theriders weight, but has an upturned or sprung-up forward portion 2 whenin use.

Intermediate the ends of the base or runner board are slide supports 3,in which is held the seat pedestal 4, which is secured in the guides 34by any suitable arrangement so 60 that the base pedestal 4 may belocked in any position intermediate the ends of the guides 3, asdesired, as shown in 'Figure III.

he pedestal 4 is secured to the top or-seat board by the bolts 7 but thepedestal 4 is G5 not locked to the base or runner board 1 but is free toslide inthe guides 3 both longitudinally and up and down, the guides 3being of a height suiiicient to prevent the pedestal 4 from jumping outfrom between 70 the guides 3 when the sled is being used with someone onthe seat. The pedestal 4 is held by the guides 3 from sidewise motion. Astraight top or seat board 5 is secured to the runner board 1 at thefront end by the bolts 75 6, and to the pedestal support 4 by the bolts7. Additional bolt holes 8 arezprovided in the seat board 5, as shown inFigures I and III so that the position of the pedestal 4 'may be changedfrom its intermediate posi- 90 tion either in a forward or backwarddirection, as desired. A seat 9 is also secured to the seat board 5. Afoot rest 10 is secured to the seat board 5 by the bolts 11 andadditional bolt holes 12 are provided in the seat 85 board 5 so that thefoot rest may be shifted from its intermediate position 11 eitherforwards or backwards as desired in a manner similar to the way thepedestal 4 is'shifted In Figure IV is shown a cross section through thebase board or runner board, which may be grooved at 13 if desired inorder to hold the sled true to its course and prevent swerving towardthe side.

It will benoted that in action the tional spring added thereto by reasonof the weight of the rider being placed on the seat 9. This seat beingplaced to the rear of the pedestal 4,has a fulcruming or lever actiontending to draw up the front end of the base board and increase thespringiness of the sled as a whole. This lever action may be increased'or decreased by shifting the pedestal out from its central positioneither for-v shifted from position T to position 8, and

also has an oscillatory movement in the guides about the bottom end as afulcrum base 95 4board 1 is turned or bent up and an addiwhen the toppiece changes its angle with respect to the runner through its sprinaction under the application of weight an encountering varying surfaceconditions.

The runner board being placed under tension by the Weight of the rider,the Whole structure is very elastic, so that when the sled goes over anunevenness in the ground, such as a bump, the sled will have a tendencyto bound upward and is very springy in its action, increasing the effectof the bumps and unevennesses that are gone over.

The sled may be made with one runner, as shown, or it can be providedwith two lor more runners or base boards separated one from the other,as desired.

It will, of course, be understood that the base runner is made from athin elastic Wood or material that may be tensed, as has been describedhereinabove.

From the foregoing description it will be seen that I have provided asimple and eicient means for constructing a .sled very springy andelastic in its action and very simple and cheap in its construction andmaintenance.

I claim:

In a sled, an unbent flexible runner, an unbent to piece having a seatportion joined at t 1e forward end of the runner and forming an angletherewith, an inflexible pedestal piece between the top piece and therunner intermediate the ends of the runner and top piece, rigidlysecured to the top piece to prevent lateral movement of the pedestal,but free and unsecured as respects the runner and so positioned with rcs)ect to the seat portion that the weight of tie operator on the seatportion will bend up the front end of the runner to form the usualupturned runner ortion, and at the same timeprovide a res lent seat forthe operator.
